Animal Companion

The Bonded is focused around their relationship with their companion, the two are nearly inseparable. Due to the divine bond between animal and bonded, the animal ages at the same rate as their companion, from the shorter lifespan of half-orcs to the long lived elves. The animal companion also has hit dice that it receives every time the bonded levels up in the Bonded class. The animal shares their bonds proficiency bonus. When the Animal Companion is reduced to 0 hit points it starts dying. At the start of every turn roll a death saving throw for the Animal Companion, follow the same rules for death saving throws as players. If the animal companion dies, the Bonded suffers disadvantage on Attribute checks and Saves until their animal companion is revived, due to feeling like part of their self has died. The animal companion is more intelligent thanks to the bond it shares, as a result they're capable of effectively wearing armor and weapons specifically designed for them. The animal companion also understands the nature of the bond the two share, knowing full well the pain one will suffer should the other fall, and that their companion can revive them if the need arises. The animal companion has it's own personality but completely trusts it's bonded partner, and does it's best to follow commands while also providing insight. An animal companion will sacrifice itself for it's bonded as long as it believe is can be revived. It takes its turn on your initiative, it will move it's speed though it doesn't take an action unless you command it to. On your turn, you can spend an action to command your companion to take the Attack, Dash, Disengage, Dodge, or Help action. Once you have the Extra Attack feature, you can make one weapon attack yourself when you command the beast to take the Attack action. If the bonded is unconscious, the animal may take a full turn, controlled by the player. The animal companion understands one language the bonded speaks, but primary communicates via a telepathic bond.

Bonded Telepathy: Can communicate with the Bonded as long as they're with in 120 feet. May communicate through words, but may also communicate via other senses such as smells, sights, and even feelings.

Recommendations: Look up Barding and Saddles (PHB. 155), Mounted combat (PHB. 198). Select the type of animal the bonded is bound to.

Revival Ritual

The divine bond has intertwined the souls of the companions, giving the bonded the ability to revive their animal through a ritual. The ritual can be cast once per long rest.

Revive Bond Companion

Divine bond (Ritual)
Casting Time: 1 hour
Range: Touch
Components: V, S, M (A piece of the companion)
Duration: Instantaneous
The bonded touches their dead animal, if it's soul is free and willing, the target returns to life with all it's hit points. This spell closes all the animals' mortal wounds and restores any missing body parts. Coming back from the dead is an ordeal. The animal takes a -4 penalty to all attack rolls, saving throws, and ability checks. Every time the target finishes a long rest, the penalty is reduced by 1 until it disappears. Casting this spell taxes the caster greatly. Until the bonded finish a long rest, they can't cast spells again, and have disadvantage on all attack rolls, ability checks, and saving throws.

Bonded Archetype

At 2nd level, the bonded chooses an archetype that defines their relationship with their animal: Knight or Bound-Shaper, both detailed at the end of class description. Your choice grants you features at 2nd level and again at 6th and 10th, and 14th level.

At 3rd level, and again at 6th level, 9th level, 12th level, 15th level, and 18th level; the animal Improves a single ability score by one and gains one Animal Ability Improvement from the Animal Companion feature or from the list below.

Keen Hearing and Smell: Grants advantage on Wisdom (Perception) checks that rely on hearing or smell.

Armor Proficiency: Grants Light Armor Proficiency if the Animal has no armor proficiencies, Medium Armor Proficiency if they only have Light, and Heavy Armor Proficiency if they have Light and Medium. May be taken multiple times.

Ability Score Improvement

When you reach 4th level, and again at 8th, 12th, 16th, and 19th level, both the bonded and animal can both increase one ability score of their choice by 2, or they can increase two ability scores of their choice by 1. As normal, you can't increase an ability score above 20 using this feature.

Extra Attack

Beginning at 5th level, the bonded can attack twice, instead of once, whenever they take the Attack action on their turn.

Bound Souls

At 7th level, the divine bond between bonded and animal strengths to sustain their very souls. If ever one dies, bonded or animal, their soul may reside within the other's body. During such a time, the carried soul may telepathically communicate with the body, and any part of that body can be considered either the bonded or animal for purposes of revival for 10 minutes after being cut free.

WIP: Descriptive flavor text

Call of the Wild

At 2nd level your animal companion gains the following bonuses:

• Increase Animal’s Strength, Dexterity, and Constitution ability scores by 1.
  You gain the following bonuses:
• You gain the ability to speak with beasts.

Pack Instinct

At 2nd level, your connection with your animal companion deepens, allowing one to instinctively know what the other is planning in combat. You learn maneuvers that are fueled by special dice called instinct dice.
Assists: You learn three assists of your choice, which are detailed under "Assists" below. Assists enhance an attack or require a special attack with the help of your animal companion. You can use only one assist per attack. You may not use an attack granted by Assist to further trigger an assist. For example, if your companion claws a creature, you may expend an instinct die to allow your companion to make another claw attack, but you can not expend another instinct die if the second attack hits, because that attack was granted by an assist. You learn two additional assists of your choice at 6th, 10th, and 14th level. Each time you learn new assists, you can also replace one assist you know with a different one.
Instinct Dice: You have six instinct dice, which are d6s. An instinct die is expended when you use it. You regain all of your expended instinct dice when you finish a short or long rest. You gain an additional two instinct die at 6th level, two more at 10th level, and two more at 14th level.

Shared Shape

At 2nd level, you can use your action to magically assume the same shape as your animal companion. You can use this feature twice. You regain expended uses when you finish a short or long rest. You can stay in your animal companions shape for the number of hours equal to half your bonded level (rounded down). You then revert to your normal form unless you expend another use of this feature. You can revert to your normal form earlier by using a bonus action on your turn. You automatically revert if you fall unconscious, drop to 0 hit points, or die. While you are transformed, the following rules apply:

• You assume the same Strength, Dexterity, Constitution of your animal companion but retain your alignment, personality, Intelligence, Wisdom, and Charisma. You also retain all of your skill and saving throw proficiency, in addition to gaining those of the creature.
• When you transform, you assume the animal's hit points and Hit Dice. When you revert to your normal form, you return to the number of hit points you had before you transformed. However, if you revert as a result of dropping to 0 hit points, any excess damage carries over to your normal form. As long as the excess damage doesn't reduce your normal form to 0 hit points, you aren't knocked unconscious.
• If your animal is not the Crafty: You can't cast spells, talk, or perform actions that require hands while transformed. You can maintain concentration on spells, and you can continue to take actions that are part of a spell that you've already cast.
• You retain the benefit of any features from your class, race, or other source and can use them if the new form is physically capable of doing so. However, you can't use any of your special senses, such as darkvision, unless your new form also has that sense.
• If the animal has spell casting abilities, you gain the ability to cast spells for them, using their spell list and spell slots. Both bonded and animal may hold different concentration spells. You can spend a bonus action to transfer concentration for a spell between Bonded and Animal.
• You choose whether your equipment falls to the ground in your space, merges into your new form, or is worn by it. Work equipment functions as normal, but the DM decides whether it is practical for the new form to wear a piece of equipment, based on the creature's shape and size. Your equipment doesn't change size or shape to match the new form, and any equipment that the new form can't wear must either fall to the ground or merge with it. Equipment that merges with the form has no effect until you leave the form.

Selective Shifting

At 6th level, you gain the ability to further control your shape change, letting you choose which ability scores you gain from your animal companion, and which you keep from your own.

Honed Instinct

At 10th level, your instinct dice turn into d8s.

Chain Assists

At 14th level, an assist can trigger another assist, however you can only use each assist once per chain. For example you could trip a creature, use grounded follow up, and then use rake, however you could not trip a creature, use rake and then use rake again.
(Design Note) this could allow for some seriously heavy turns, ensure wording on Assists only allow Assists on targets hit, do not allow choice of targets, otherwise the Assist chain could use all instinct and allow the Bonded and Animal to move around the entire field. That or save this ability for level 18 or 20, because getting upwards of 14 attacks in a turn is insane balance wise. I’m ok with the idea of the Bonded going all out on a single target, as long as they continue to hit and chain assists, it’s a cool power that builds to some really cool abilities.
